The USART devices in Microchip SoCs have an ISO7816 mode. It allows to let the USART managing the CLK and I/O signals of a smart card. Changes: - v2 - uart_get_iso7816_config: check there is an iso7816_config function - use IOCTL macros to generate the IOCTL number - check that reserved field is not used - remove debug logs - check that the iso7816_config is right before doing any action - change the error from nack and max iteration status to a debug message - remove patch 3 as it concerns both rs485 and iso7816 to think more about the need of adding a lock or not Nicolas Ferre (2): tty/serial_core: add ISO7816 infrastructure tty/serial: atmel: add ISO7816 support arch/alpha/include/uapi/asm/ioctls.h | 2 + arch/mips/include/uapi/asm/ioctls.h | 2 + arch/powerpc/include/uapi/asm/ioctls.h | 2 + arch/sh/include/uapi/asm/ioctls.h | 2 + arch/sparc/include/uapi/asm/ioctls.h | 2 + arch/xtensa/include/uapi/asm/ioctls.h | 2 + drivers/tty/serial/atmel_serial.c | 170 +++++++++++++++++++++++++++++++-- drivers/tty/serial/atmel_serial.h | 3 +- drivers/tty/serial/serial_core.c | 60 ++++++++++++ include/linux/serial_core.h | 3 + include/uapi/asm-generic/ioctls.h | 2 + include/uapi/linux/serial.h | 17 ++++ 12 files changed, 256 insertions(+), 11 deletions(-) -- 2.12.2
